Assignment Operators in C | Shorthand operators in C
Assignment/shorthand operators are used to update the value of a variable in an easy way. There are various assignment operators provided by C language.
- =
- +=
- -=
- *=
- /=
- %=
- &=
- |=
- ^=
- <<=
- >>=
Operator |
Description |
Example |
| = | It is used to assign some value to a variable. | A=10 |
| += | It is used to increment the value of a numeric variable by adding some value to the existing value. | A=10 A+=5 [A=A+5] A=15 |
| -= | It is used to decrement the existing value of a numeric variable by subtracting some value from the existing value. | A=10 A-=5 [A=A-5] A=5 |
| *= | It is used to multiply existing value of a numeric variable by another value and then store the result in it. | A=10 A*=5 [A=A*5] A=50 |
| /= | It is used to divide the existing value of a numeric variable by another value and then store the result in it. | A=10 A/=5 [A=A/5] A=2 |
| %= | It is used to divide the existing value of a numeric variable by another value and then storing the remainder in it. | A=10 A%=5 [A=A%5] A=0 |
| &= | It is used to apply bitwise AND operator on existing value of a numeric variable by another value and then storing the result in it. | A=10 A&=7 [A=A&7] A=2 |
| |= | It is used to apply bitwise OR operator on existing value of a numeric variable by another value and then storing the result in it. | A=10 A|=7 [A=A|7] A=15 |
| ^= | It is used to apply bitwise XOR operator on existing value of a numeric variable by another value and then storing the result in it. | A=10 A^=7 [A=A^7] A=13 |
| <<= | It is used to apply Bitwise LEFT SHIFT operator on existing value of a numeric variable by another value and then storing the result in it. | A=10 A<<=1 [A=A<<1] A=20 |
| >>= | It is used to apply Bitwise RIGHT SHIFT operator on existing value of a numeric variable by another value and then storing the result in it. | A=10 A>>=1 [A=A>>1] A=5 |
Example 1
Program to demonstrate shorthand operators in C |
Output (Line wise) |
#include<stdio.h>
int main()
{
int a=20;
|
|
a+=4;
printf("\na=%d",a);
|
a=24 |
a-=13;
printf("\na=%d",a);
|
a=11 |
a*=6;
printf("\na=%d",a);
|
a=66 |
a/=5;
printf("\na=%d",a);
|
a=13 |
a%=5;
printf("\na=%d",a);
|
a=3 |
return(0); } |
Example 2
Program to demonstrate the use of shorthand operators in C. |
Output (Line wise) |
#include<stdio.h>
int main()
{
int a=10;
|
|
a&=7;
printf("\na=%d",a);
|
a=2 |
a=10
a|=7;
printf("\na=%d",a);
|
a=15 |
a=10
a^=7;
printf("\na=%d",a);
|
a=13 |
a=10
a<<=1;
printf("\na=%d",a);
|
a=20 |
a=10
a>>=1;
printf("\na=%d",a);
|
a=5 |
return(0); } |
